Please do not attempt lip-liner removal with any laser as it has a high probability of oxidizing (turning PERMANENTLY black). The only cosmetic tattoos we can safely remove are dark inks, usually seen in eyebrow tattooing and microblading. Even then, a ‘test spot’ is recommended to see if the ink will turn darker or reveal that red and/or yellow was mixed in, which would require further treatment with the 532nm wavelength. If you ever have the slightest doubt about how an ink will react, please perform a test spot and evaluate it in about two weeks. If you have any questions about this, you can email me at firstname.lastname@example.org. The example below is published with the patient’s permission to warn others about the risk of treating cosmetic tattoos without first performing a test spot.
